Cargo Features

[dependencies]
presence = { version = "0.5.2", default-features = false, features = ["pgp", "ed25519", "x25519", "signature", "chrono"] }
default = chrono, ed25519, pgp, x25519

These default features are set whenever presence is added without default-features = false somewhere in the dependency tree.

pgp default = signature

Enables pgp

ed25519 default = signature

Enables ed25519-compact

x25519 default

Enables x25519 of ed25519-compact

signature ed25519 pgp = base64

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
